The crazy thing is if you want to make easy meals just get a slow cooker. Bang the ingredients in first thing, by the time the kids get home from school you can have stews, chilli, currys. At the opposite end of the scale, a stir fry with fresh ingredients takes less than 15 mins is inexpensive and full of veg, most of the westernised Chinese sauces are dead easy to make.
Im pretty sure most of it comes down to laziness and a couple of generations of not learning basic cooking skills. I wouldnt mind but there's thousands of videos on YouTube showing you how to do it, its not like the old days of a recipe book where you had to read and understand it.
One thing that does irritate me however is how outrageously expensive fish is in the UK. Half the problem is that unless its Haddock, Cod, Salmon or Tuna people wont buy it so it gets sold abroad.
